Stunned. Phenomenon. Waterfall on the Sun.
May 5th Adisak Sukvisut – Astronomical Information Officer National Astronomical Research Institute (SorDor.) Posted on Facebook, National Astronomical Research Institute on Astrophotographer Found a strange phenomenon on the sun that looks like a waterfall and it is higher than 100,000 kilometers, with details that
This image was captured on March 9, 2023 by Argentinian astrophotographer Eduardo Schaberger Poupeau. While taking the picture, he did not notice the strangeness. but came across it while importing the image onto the computer It appears to be something that resembles a “waterfall” in the sun.
Academically, this phenomenon is called Polar Crown Prominence or #PCP It is a phenomenon on the sun that resembles a stream of water falling to the ground. There is a name that is called playfully. Plasma Waterfalls or Plasma Waterfalls
PCP is a common occurrence on the Sun. It tends to occur more frequently near the anniversary of the solar cycle (regarding every 11 years) known as the Solar Maximum, as do other plasma-related solar phenomena.
PCP formation is similar to solar flares. It is the result of the unevenness of the Sun’s magnetic field. This makes plasma, an ionized gas, Ejection from the surface of the Sun. For PCP, it usually occurs near the poles of the Sun. Both the north and south poles, regarding 60 to 70 degrees latitude, this time the plasma rising from the sun’s surface is estimated to reach regarding 100,000 kilometers. (While the diameter of the Earth is only regarding 12,700 km.)
Although the PCP looks like a drop of water that should flow consistently. But the drop of plasma within each PCP is not a free fall like a waterfall on Earth. because it is related to the intensity of the magnetic field at each location As a result, the plasma shoots at a maximum speed of 36,000 kilometers per hour. This is faster than experts can calculate from the intensity of the magnetic field. And it’s still a mystery that researchers are trying to find an answer to.
A 2021 study published in the journal Frontiers in Physics noted that PCP undergoes two transition phases during eruption: the slow phase, when plasma slowly rises from the sun’s surface; and the “rapid phase” is when the plasma is accelerated by a magnetic field to its highest position. It is possible that extreme plasma velocities might be involved in this process, however, astronomers need to do more research to determine the exact reason.
Solar physicists are interested in the phenomenon of solar plasma plumes. This is because they involve coronal mass ejections (CME), supermassive plasma ejected from the Sun’s atmosphere, while PCP is plasma bound by the Sun’s magnetic field. causing the plasma to gush out Duan goes back and forth to its own surface. does not fall out of the atmosphere It is therefore of interest to nuclear physicists.
From this PCP process, if we continue to study more in-depth information It might help us improve nuclear fusion reactor experiments. that is clean energy And it is possible that in the future it will replace the fossil energy we are using today.
